Vintage portrait photo circa 1860s of stage actor John Wilkes Booth - the man who assassinated US President Abraham Lincoln. Booth (1838 - 1865), a Confederate sympathiser, fatally wounded Lincoln by shooting him in the head on April 14 1865 at Ford's Theatre in Washington DC. Booth escaped the scene but was tracked down to a barn in Virginia and fatally shot by Union soldiers 12 days later. Four fellow conspirators - Lewis Powell, David Herold, George Atzerodt and Mary Surratt - were subsequently tried and executed by hanging for their roles in the murder conspiracy. The plotters had also intended to kill Vice President Andrew Johnson and US Secretary of State William H Seward. Photographer unknown.
